Straightboost Performance wideband knock sensor kits are specifically designed to work with the sophisticated knock detection circuits in many modern ECUs, such as the FuelTech, ECUMaster EMU, Link, Haltech, Microtech, DTA Fast, Megasquirt and many others. The knock processing chip in most of these ECUs are designed to take advantage of wideband, or flat response, knock sensors. For many years most knock sensors were designed to generate an output voltage only around a preset frequency based on engine characteristics, this was a limiting factor for signal processing. The drawbacks those older OEM sensors were their inability to separate knock from noise. With these modern ECUs with state of the art signal processing, wideband sensors can be used, allowing the EMU to process the signal in its full range and look only for sounds that actually represent knock. The EMU is also able to filter the signal by crank degrees so that it only monitors the sensors at engine positions where knock is likely to occur. The use of Straightboost Performance wideband knock sensors allows for greater sensitivity to knock and greater control of the engine, allowing the tuner to maximize power output with the confidence that the EMU will employ engine protection strategies when knock is detected.
Flat response knock sensors can be used on any engine, but please verify the thread size/pitch before ordering. This kit includes a M12x1.25 stud which fits Toyota JZ engines and others (See Below).
Each kit includes the following:
1. Brand New and Genuine Bosch knock sensor.
2. Mounting stud that will work with most engines with M12x1.25 thread for the knock sensor port. (Please read below for more info).
3. M8x1.25 Retaining Lock Nut.
4. Electrical connector with terminals and seals or a pigtail. (Select option in the drop down menu).
If your engine is not listed below, check the thread in your engine block or contact us prior to purchasing in order to verify fitment. (The thread can be verified by using a M12 bolt with 1.25 thread pitch.)
Toyota: 1JZ,2JZ,1UZ,2UZ,3UZ,3SGE,3SGTE
Nissan: RB20,RB25,RB26,CA18, SR20, KA24, VG30

Nice little kit. Sensor is genuine Bosch. I got it all set up in my tuning software. Works like a charm.
